Application filed August 2], 1906. Serial No. 275,020.

.To all wk/TH, it 7720!] concern.-

Be it known that I, OSCAR J. SEEnaUsEN, a citlzen of the United States, residing at Chicago, in the county of Cook and State of 1 and particularly pointed out in the claim.

In the accompanying drawing, forming a part of this specification, Figure 1 is an elevation, partly in section, of a well-known type of lamp to which my improvements have been applied. Figs. 2, 3, and 4 are enlarged detail views taken from Fig. 1.

Referring to the drawings, 2, 3, 4, and 5 represent the arms or members of a frame of ordinary construction. A portion of the frame is used as a conduit in the well-known manner and to that end the members 3 and 4 are hollow. The member 3 communicates with the nipple 6, leading to the source of liquid-supply, such as a reservoir, from which the liquid is fed by gravity or by pressure.

7 represents the retort or gas-generating tube, and same connects the arms 3 and 4.

Arms 2 and 5 may be either solid or hollow,

' and if the latter they will be closed, especially arm 2, against communication with the conduit, comprising tubes 3, 7, and 4. The arms 2 and 5 of the frame may be termed the dead arms and the others the tubular arms. The upper arms 2 and 3 of the frame or hanger are each shown with. a reverse curve but any suitable configuration other than that shown Will be equally as well adapted for the purpose of my invention. The arms of the frame are connected by ballcastings 8 9 10 and the nipple 6, the casting 8 being recessed to provide communication between tubes 3 and 7 and the casting 9 similarly recessed or hollowed to open communication between tubes 7 and 4. The casting 10 is also hollowed out to provide a chamber communicating with the tube 4, and said casting 10 has an upwardly-projecting nipple or neck 11. The arms of the frame or hanger are preferably screwed into the ball-castings and then soldered to insure against leakage.

12 is a Bunsen tube which holds the gallery, mantle, and glassware, and said tube is of exactly the same diameter as to interior opening as the diameter of the passage through arm 4 to insure a free passage of the gas, and thus obviating the noise incidental to a cramped outlet. The glass globe or chimney 13 is shown provided with a series of circularly-arranged holes arranged in a lower plane than the burner. These holes are for the purpose of providing an abundant flow of air from below to take place of the heated air rising rapidly within the globe or chimney 13. The generating-tube 7 comprises a valvebody 16, 'which has threaded engagement with or is soldered to, or both, the casting 8. In this casting is placed a disk of very fine brass-gauze cloth 17, which arrests any impurities which would otherwise enter the generator 7 and produce smells or clog up the fine needle-opening, to be referred to hereinafter.

Connected with the valve 16 is a seamless brass tube 18, which is also preferably both threaded and brazed to the valve. The tube 18 has 011 its opposite end a threaded portion 19, which has threaded engagement with a threaded socket 20 in a removable tip 21, provided with a minute passage 22, which leads from tube 18 to a tube 23, communicating with the casting 9.

To one side of the vertical plane of the burner I or Bunsen tube 12 and within the tube 18 is an asbestos tube 24- through which the gas or liquid fuel is passed from the valve 16 to the superheatingchamber 24 of the tube 18. This chamber 24 is directly above the flame. Within the socket 20 of the tip 21 is also a piece or disk of fine brass-gauze cloth 17, which arrests any particles in the gasolene or vapor which may have passed the gauze 17 such as paraffin or other precipitated matter. The two gauze tips straining the gas and liquid both before and after expan sion in chamber 24 will ordinarily insure a free opening through the passage 22, and when it has for any reason become clogged the tip may be quickly removed as is indicated in its separation from adjoining parts in Fig. 4. Loosely mounted on the tube 23 and having threaded engagement with nipple 2-1 is a sleeve 25, having a series of openings 26. This tube serves as an air-mixer for the vapor issuing from the tip 21.

' The air-mixer or sleeve has a combination drip-cup and flame-guard 27, which is in the form of a hollow'shell extending around the openings 26 and fitting closely to the tube 25 for about one-half of the circumference of said tube. Asshown in Fig. 1 the contour of the drip-cup is such as to leave a clear space all around the tube on that portion of same which has the perforations or openings 26. The air is thus freely admitted to the holes on the underside of the tube and opposite the bottom of the dripcup. As the drip-cup completely shields the tube 25 in its horizontal plane against ignition through the holes or openings 26 from the flame which heats the chamber 24, the protection is ample for entire safety and any drippings of impure matter or raw gasolene through the openings 26 are caught in the cup and the inflammable matter evaporated and the resultant gas drawn in with the air through the openings 26 to be utilized as a fuel instead of being permitted to fall on the floor or carpet. Four openings 26 are preferably provided and these openings are made of such size as to admit, through siphonage, the proper amount of air relative to the volume of gas issuing through the opening in the tip 21. Through this arrangement of drip-cup and flame guard surrounding and guarding the openings 26 from below these openings can be made of any suitable size and arranged in any suitable manner Without reference to the liability of drippingat the point of air-admission, such dripping being automatically collected, evaporated, and utilized, thereby saving waste and liability of-damage through the soilingby or ignition Another very important funcof drippings. tion performed by this drip-cup and shield arranged to surround the openings 26 in their horizontal plane is the protection it affords against the blowing out of the lamp.

A large number of lamps of this class are unsatisfactory in their operation by reason of the fact that sudden gusts of wind or drafts check the flow of gas through the mixing-chamber, shutting off the pressure and flow to the burner, and consequently extinguishing the flame. The shield 27 prevents accidents of that kind and insures a steadv witnesses.
